I'm working on a high, mid-control foot clutch. I'll post a pic when I get back out to the garage.

My question is - what's the deciding factor on rod vs. cable for a foot clutch? I have a pretty straight shot to the clutch arm and could use a rod, but I think they look not as clean as a cable. I can also switch over to a shorty clutch arm and use a cable.

The only thing I can think of as a benefit either way is that a cable equals the risk of breaking.

Is there some logic around how you choose. Seems like most foot clutches use a rod...anyone have any insight as to why?

Thanks.

Man, I'll exploit any opportunity to get rid of a cable.
Rod, nice and direct. Simple and tough.

I'd Have to agree, I hate cables, the set up in those pics look awesome !

Nice job on those controls Dr.

Cables stretch over time. Usually in an inopportune time. Rods never will.

Doc -

Can I see a pic of how you tie the linkage to the clutch rod? Is there a pivot on the front of the trans? It looks like that setup would be pulling the arm down. They look great though.

Here's the test piece I was making. I have a straight shot to the arm.

I use the Fab Kevin foot clutch cable on my '68 and feel like it gives me a much longer sweet spot. I also have a rod (actually a welded chain) on my cone shovel that works just fine but a much shorter sweet spot.

Ah, okay. Take a look where the rod meets the arm; I made a tube that slides over the clutch arm (rosette welded) with that teardrop shape on the end. Bolt goes through to the rod (threaded end with a hole in it).

I see what you're saying, the geometry looks funny...but the bend in the arm makes it all work fine.

Ah - that makes sense. Thanks Doc.

I've snapped many a cable, never broke a rod
